Matsya Purana — Genealogy and Classification of Sacred Fires
काम्यास्विष्टिष्वभीमानी रक्षोहायतिकृच्च यः सुरभिर्वसुमान्नादो हर्यश्वश्चैव रुक्मवान् //
kāmyāsviṣṭiṣvabhīmānī rakṣohāyatikṛcca yaḥ surabhirvasumānnādo haryaśvaścaiva rukmavān //
In the kāmya and sv-iṣṭi offerings, the one designated as Abhīmānī; and the performer of the Rakṣo-hāyati rite; also Surabhi, Vasumān, Nāda, Haryaśva, and likewise Rukmavān—these are the ritual appellations to be known.
This verse does not describe pralaya; it catalogues ritual designations and a protective rite name, indicating the Purāṇa’s concern with correct liturgical terminology rather than cosmology here.
It supports dharmic duty by stressing correct identification of rites and their appellations—knowledge a householder (or a king maintaining public rites) would need to sponsor offerings and protective ceremonies properly.
The significance is ritual: it lists names/epithets connected with iṣṭi offerings and mentions a rakṣas-repelling rite (rakṣo-hāyati), highlighting protective liturgy rather than Vāstu or temple architecture.
